appengine: fix test enum values for app_engine_bundled_services

[riddhi-shivhare]

Description

This PR fixes acceptance test enum values and ensures proper state tracking for app_engine_bundled_services on google_app_engine_standard_app_version:

1. Fix Inconsistent Enum Values in Acceptance Tests: Updates testAccAppEngineStandardAppVersion_bundledServicesUpdate to use full BUNDLED_SERVICE_TYPE_... enum values (BUNDLED_SERVICE_TYPE_MAIL, BUNDLED_SERVICE_TYPE_USERS) instead of short strings, resolving schema validation errors in tests.
2. Ignore Read Drift: Retains ignore_read: true to prevent state drift when the GCP API Gateway omits appEngineBundledServices in GET responses.
3. Doc Formatting: Fixed mixed quote formatting in StandardAppVersion.yaml description.

Testing

• Built local google-beta provider and verified clean generation.
• Validated acceptance tests with full enum strings.
